Value Collection 307102PR Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 307102PR is a hex socket cap screw designed for secure, high-strength fastening in mechanical assemblies, fixtures, and equipment. It features a 5/16-18 UNC thread and a 1/2 inch length under head, making it well suited for applications where a low-profile socket drive connection is required. The screw is fully threaded and driven with a 7/32 inch hex key. Constructed from alloy steel with a black oxide finish, it meets ASTM A574 standards for mechanical fasteners. This screw is installed by machinists, maintenance technicians, and trade professionals working on equipment, enclosures, and structural assemblies.

This fastener is commonly used in industrial and commercial maintenance applications where a high-strength, corrosion-resistant socket cap screw is needed. The black oxide coating provides moderate corrosion resistance and reduces light reflection, making it appropriate for enclosed mechanical assemblies, machine guards, and equipment panels. It is suitable for use in both original equipment manufacturing and field repair scenarios where 5/16-18 UNC threading is specified.

Key Features

• 5/16-18 UNC thread for standard inch-series fastener compatibility
• 1/2 inch length under head with full threading along the entire shank
• 7/32 inch hex socket drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction meets ASTM A574 mechanical fastener standard
